提出了一种射频（RF）功率收集系统，用于为医疗设备（例如，可穿戴或可植入传感器等）。所提出的系统允许医疗设备即使在可用的RF能量很少的情况下也能运行。功率接收器由印刷天线、调谐良好的整流器、电源管理芯片和电荷存储设备组成。对于工作在2.4GHz的100mW发射器，4F超级电容器可以无线充电至3V。未来的设计考虑进行了讨论，即。灵活性的收获电路和宽带收获。
A Radio Frequency (RF) power harvesting system is proposed to wirelessly power medical devices (e.g., wearable or implantable sensors, etc). The proposed system allows medical devices to operate even when there is little RF energy available. The power receiver consists of a printed antenna, well-tuned rectifier, power management chip, and a charge storage device. For a 100mW transmitter operating at 2.4GHz, a 4F super-capacitor can be wirelessly recharged to 3V. Future design considerations are discussed, viz. flexibility of the harvester circuit and wide band harvesting.
